What is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?
Cyclins are proteins that are synthesized at specific times during the cell cycle and associate with cyclin-dependent kinases (CDKs) to form a catalytically active complex. This complex regulates the progression of the cell cycle by phosphorylating specific target proteins.
What questions might scientists have asked following the discovery of cyclin?
Scientists might have asked how cyclin levels are regulated during the cell cycle, what specific role cyclin plays in regulating cell division, and whether abnormalities in cyclin expression or function are associated with diseases like cancer.
Which of the following is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?
Cyclin is a protein synthesized at specific times during the cell cycle that associates with a kinase (CDK) to form a catalytically active complex. Cyclin-CDK complexes regulate the progression of the cell cycle by phosphorylating various target proteins.
What is the path of an egg from production to implantation of the fertilized egg?
An egg is produced in the ovary, released into the fallopian tube during ovulation, fertilized by a sperm in the fallopian tube, then travels down to the uterus where it implants in the uterine lining for further development.
What is the fertilized egg called during implantation?
The fertilized egg is called a blastocyst during implantation. The blastocyst is a multicellular structure that forms from the fertilized egg as it develops and prepares for implantation in the uterine lining.
What happen in a cell if production of cyclin is halted during a cell cycle?
If production of cyclin is halted during a cell cycle, the cell cycle will be arrested at a specific checkpoint until the levels of cyclin are restored. Cyclins are proteins that regulate the progression of the cell cycle by binding to cyclin-dependent kinases (CDKs). Without cyclin to bind to CDKs and activate them, the cell will not be able to progress through the cell cycle.

The substances that control the cell cycle and the entry into mitosis are known as cyclins and mpf mpf stands for?
MPF stands for Maturation-Promoting Factor. It is a complex of cyclin and cyclin-dependent kinase that regulates the cell cycle progression and entry into mitosis. Cyclins are proteins that fluctuate in concentration during the cell cycle and bind to cyclin-dependent kinases to regulate their activity.
How many times does the fertilized cell divide during meiosis?
The fertilized cell divides twice during meiosis, resulting in the formation of four haploid daughter cells.
Describe the relative concentrations of MPF and its constituent molecules throughout the cell cycle?
MPF - complex of cyclin and cdk that initiates mitosis by phosphorylating protein and other kinases; highest concentration at metaphase Cdk - levels are constant throughout the cell cycle Cyclin - levels vary because it is broken down by MPF after anaphase
What does a fertilized cell develop into during the cell cycle?
an organism
What develop into a fertilized cell during the cell cycle?
an organism
The fertilized ovum divides and implants into the wall of the uterus during which stage of gestation?
The fertilized ovum implants in uterine in blastula stage
